We ran the search algorithm twice with the same basic settings, including the operation pool and the maximum number of layers. Since there is a random sampling process during the warm-up stage, the final solutions found by the algorithm are expected to be different. The operation pool consists of CNOT gates between every two qubits, the Placeholder and the single qubit rotation gate [1]}:
\(Rot(\phi , \theta , \omega )=R_Z(\omega ) R_Y(\theta ) R_Z(\phi )=\left[\begin{array}{cc}e^{-i(\phi +\omega ) / 2} \cos (\theta / 2) & -e^{i(\phi -\omega ) / 2} \sin (\theta / 2) \\e^{-i(\phi -\omega ) / 2} \sin (\theta / 2) & e^{i(\phi +\omega ) / 2} \cos (\theta / 2)\end{array}\right]\)
